TDI mpg vs engine temp

[lloydy]

Not really sure what i have, i'm not aware of another switch for brake lights?.. Just popped out and looked at the pedal switches, brake has 5 wires, clutch 2 if that means anything?

[max and caddy]

5 wires! Sure it's not 4? Was there 2 hydralic switches on the master cylinder?

[lloydy]

just looked again, 2 wires are doubled up in one pin. So there is 4. Presume that means ive got some super duper set up?..

[max and caddy]

Kinda...but it's the later switch...mine isn't and that why I get the code, the pressure sender fault concerns me more...will keep an eye open for a spare ecu for the glove box just in case!

For the pressure sensor, presuming yours is a 68pin ECU, pull the PCB out of the box and check both the soldered joints, the internal pipe ,more likely make sure the sensor is not full of engine oil.
For our TDis we do use a relay for brake switch, using 87a to switch earth/pos depending on ECU with factory T3 brake switch operating relay

Missed that almost as though you were watching me...

I've got the 4-pin switch, nevertheless I've had two, maybe three times when I've had a 'brake pedal monitoring' DTC. I think I'll ditch the mechanical switch and simply use the T3 brake lamp wire plus a 5-pin relay for the inverted signal. I think this is the most likely to give trouble-free operation.

Ps. Soz to drag this thread further off topic.

It works great Andy, never seen any DTC's on our conversions, we put relay under rear seat but if you don't want clicking from relay the fit it in rear Jcn box

[syncroandy]

never seen any DTC's on our conversions

you're not trying hard enough!

[mazz]

Should read " never seen brake pedal DTC's"

[lloydy]

couple more fill ups...

Settling down nicely to 28.5 :k

[lloydy]

looking forward to what i'll get when i'm not chucking loads of unburnt diesel out the exhaust!

[HarryMann]

Hehe! I've been trying to do that for years....
Either too much fuel or too little oxygene.
