Coolant and Heating Instrumentation malfunction
From VW T25(T3)-Tech
Jump to navigationJump to searchnrxx: 1987 1.9 DG Had a non functioning temp guage for a while now, did work but hada few weeks of low readings and now nowt.
Got a new sensor for side of thermostat housing, checked for power, ok. Changed and made no difference. Noticed another sensor hidden around the front of the stat housing. Should I have both of these and if not, which one should be coolant guage sensor? Haynes appears to say that the one I changed should be a fuel injection temp sensor and that the one hidden round the front is the one I want (obviously with a DG I don't have injection!).
Also... Do I need to remove the actual instrument cluster to check the multi-pin or just the cover?
