2.1 fuel injection injectors, share you experiences

[Aidan]

I have only used genuine VW / Bosch injectors.
I have had a few sets cleaned/tested by the place in Hull that no longer seems to be trading, and the results were good, I sold a few sets to members on here and the customers also seemed happy, certainly I never received any negative feedback.
The cleaned tested injectors completely sorted my slight loss of power, slightly unbalanced running on Edna, and made sense as according to the before test one of the injectors was more than 10% down on flow compared to the others and they were all a bit down on flow as you'd expect, especially as I was running 80% of the time on LPG, so fuel might not always have been optimal and lpg soaked air around the nozzles might not be ideal - that's how I noticed the imbalance, it was noticeable compared to when running on LPG. When returned they were all within a % or two of each other and all around 95% performance according to the paperwork, which may or may not have been true but the performance matched.

So I have a few questions and I'm hoping people will share......

Who, other than the place in Hull, have people used for cleaning/testing and how was it ? Links helpful, especially if recent and positive experience. Has anyone bought refurbished units from the place in Aberystwyth for example ?

Has anyone tried the green aftermarket Chinese made injectors that are for sale on Ebay, black body, white printed Bosch part number, and how did you find them ? I have a set, unused on the shelf, which I now suspect was a waste of a couple of hundred quids.

Has anyone run the 0 280 150 711 Bosch injectors which are really for the Saab 2.0/2.3 naturally aspirated engine from the mid/late 80s/1990, again how did you find them, and which engine code are you running them in ? They are identical in fitment to ours, same resistance, but flow roughly 5% more fuel, (Saab makes more power than WBX so that makes sense, all the Bosch parts were specifically tuned to suit the engines) so there maybe a difference between a digijet and a digifant set up in use.

Has anyone tried the ?reproduction/?licensed Bosch 0 280 150 206 yellow injectors available from Germany, on Ebay, shiney shiney, and sold in box marked AESVK11, and have a 9zwo8.com label, and which are on the 9zwo8.com website - they look pukka, fitted with Cohline hose.

Who has used the EV14 Bosch injectors from Brickwerks in the UK, and elsewhere; which version injector was it (I believe there may have been a hose version which is nla, so now the only one available is the push in one so requires a replacement fuel rail which they are supplied with) and again how was/is it. I am guessing it's the 150g/min version that is sold into our market, which is the same flow rate as the Saab variant (above) of the original Bosch injectors.

Just trying to gather together the most up to date info for those still running these engines to help peeps get the best value for money and best/as close to original performance. I've heard various things but nothing beats real world experience compared to hearsay, and I, like many on here, am a little bit out of the loop since most of the world became fb/whatsapp centred and online forum averse.

No need for 'I have a 2.1 but I run it using a carb because ....' comments, this is to help peeps keep their fi systems running optimally. If you have a 1.9 with fuel injection then please share, afaik they weren't sold in the UK, but there will be imported ones here now. If you have a modified WBX, and run fi then definitely please share, especially if you have an aftermarket injection set up.

Thank you

I bought four from here before Bricky sold them. They are the ones without the fuel rail.I only ran the van for a while before it went away

I can't comment on T3 related injection systems but I know that my car mechanic sends any injectors here

I've had injectors from ford mondeos and volvos sent here and have been pleased with the performance afterwards.

SAAB certified trainer at your service (Yes, I am a Saab certified trainer !)

The injectors you refer to are used for the L-Jetronic system of the naturally aspirated 16 valve 2.0 litre Saab engine, B202I (no 2.3 litre those years).
These are NOT identical in fitment, as the stainless steel fuel rail holds the injectors in place and seals against them with O-rings. 
The injectors which are identical in fitment of Saab, Volvo and Mercedes Benz, are those used with the D-Jetronic system between 1969 and 1974/5. I will be able to source some part numbers next month when I will be in Israel again, and look at my old hardcopies of the parts manuals.
As far as I know, all Bosch injectors of these 2 types of fitment, have the same or very close electrical resistance. They differ in fuel capacity, hence the colour code.

A couple of years ago I bought a Beck Arnley set for next to nothing off RockAuto, advertised as being suitable for the Volvo 240 range and VW Vanagon. I measured the flow rate as being slightly higher than stock. They ran perfectly well, but as expected, fuel consumption was higher. I suppose Digifant could deal with the higher rate. That added two future projects to my list: slightly reduce fuel pressure with an adjustable regulator or shorten the injector pulse length by a small percentage. I got as far as acquiring a Malpassi regulator before another project took priority. I still intend to pursue them if my current efi project, which is also on hold, fails. So many projects.

This where it gets very confusing as I have a set of these 711 injectors I bought from Latvia, genuine Bosch boxes, with QR code that check out as genuine, and physically they are exactly the same as the T3 206 part number and most definately have the top hose set up as you can see here



old VW right, new Bosch 0 280 150 711 left

in the same way I have found pics of 762 and 792 part number injectors some push fit, some top hose, same part number - I know also of some one who has in stock new 792 part numbers having yellow plastic, and others with a brown plastic

Useful to know the colour is related to the resistance (in our case nominal 16ohm) but doesn't explain why I have seen genuine (or believed to be genuine) VW ones with green plastic with the same 206 part number moulded into the plastic (not printed like the Chinese fakes) - which reminds me I must check the resistance of the fakes

tbc hopefully

I have a set of these.......

EV14 on the Oettinger 3.2, its 1.5x DJ with a warm cam so they seemed a fair match, I was intrigued by the modern (piezo?) four hole fogger type bozzle which is supposed to give better fuel atomisation and a better burn compared to T3 OEM pintle solenoid injectors; trying for higher efficiency rather than outright higher flow rates.

I have yet to set up the idle mixture or connect the secondary lambda sensors and gauges to monitor both banks of cylinders.

I have a set of recon original yellows if they don't deliver or fail prematurely.

here is my experience of some of the new injectors now appearing.. 

i recently (a few weeks ago) bought a set from ebay supplied by a welsh firm, autofirma.. this link. (ebay advert says based in borth but registered company hq is down in penygarn in dyfed) 

i had the 2.1mv engine rebuilt for my trakka (1990 syncro) and also replaced all rubber hoses, pipes, sensors, electrical components, belts  etc that were looking dated.  my old injectors were refurbished (by the firm in hull that aidan referred to) a few years ago and were now very crusty and quite possibly the original set, but working fine.. nevertheless i decided to replace with the new ones from autofirma.  their part number 0280150206 listed on their site corresponds to the bosch originals, so confidence was high. 

after sorting out timing and approximate mixture and idle, the van ran quite rough.. it would start easily cold or hot, drive ok-ish as long as the throttle pedal was being exercised, though subtle pressure off idle led to jerkiness.. but the main problem was that after coasting (eg long downhill) whilst in gear, when the pedal was depressed there was zero response from the engine.. nothing -- the engine hadnt stalled and was still in idle.  after some pumping the engine would revive with a splutter and occasional backfire then continue driving as before until the next downhill coasting with this same reproducible problem.  since i had changed many components in the reinstalled engine i did not suspect the new injectors. 

i checked (ie removed and set the throttle position switch according to bentley) since it was as if the tps was not sending a wakeup signal back to the ecu.. , checked wire continuity on all relevant wires and voltages at the tps, checked resistances on the afm flap and connector checked earths,  checked the coil,  checked the ecu terminal resistances and voltages, changed the fuel pressure regulator, changed lambda sensor, changed rotor arm and cap.. -- basically followed the bentley diagnostics ..everything checked out ok and the  behaviour pattern continued.  eventually i swapped out the new injectors for my old crusty set and the problem went away and the trakka is now driving wonderfully again. 

so i am assuming one or more of the injectors are faulty. 

i am still in discussion with the company.  their communication speed has been fantastic but they maintain it is unlikely a fault on their injectors. .  it seems they have sold lots of these and i am the only one who has reported an issue  so they find it hard to believe there is a fault with their injectors.   i havent checked the injectors for spray pattern or flow rate myself as the evidence to me indicates they are faulty so i have now returned them and will let the company decide to repair, refund or replace  (i am just outside the 30 day period of returning faulty items as i only reinstalled the engine a couple of weeks ago, but bought the injectors three weeks prior to that in readiness for the rebuild).   but the set sent to me did not work as expected. 

so i would be interested to know if anyone else has bought these and if they had any issues.  as they say, i am the only one to report any
problems so i just might have been unlucky with the one faulty set. 

more of us will be needing replacement injectors give the age of our vehicles so i am extremely interested in the club's experience and knowledge to source reliable new injectors for our vehicles...  if the company decide to repair or replace, i will swap them in and pass on my results later.
