Passat EPC Warning Light

I started to develop a problem with my Passat when after about 15 minutes of the car running it started to lose power momentarily and the EPC light would come on. Eventually this was accompanied by the catalytic converter warning lamp.

Car would then stall when you came to a standstill and would be hard to start again, but would eventually get going. This just went on every day for the weeks I should have got it fixed.

I took it to the Volkswagen dealer and they were talking about trying lots of things including a compression test and wanted over £300. All without a guarantee of actually fixing the problem! I got the impression that they didn’t know what the problem was.

My Vagcom diagnosed it as a problem with engine speed sensor – also believed to be known as the crank sensor. I got a local, trusted mechanic to change it for £70 and it’s been fine since.

    I have the same problem, My traction control warning light came on after doing 105 miles; then 5 minutes later glow plug warning light came on. Do I need to change the speed sensor?

      Hi Karen. I’d take it to any good local mechanic who will be able to plug in the correct diagnostic tool. They’ll then tell you what needs fixing.

    I went to look at a VW Passat1.8 turbo on Sunday at a dealership,it has 83,000 miles, and A full service history.
    but when I test drove the vehicle it was crunching in second gear and third gear and from fourth back down to 3rd also crunching, The dealer said he would have the car up and running by Sunday end of this week. Please tell me people am I nuts going after this car?
