Having run a scan with an OB11 scanner and reading some material which explained the codes, the fault was was traced to the crankshaft sensor. So, I took my car to be repaired at a local garage and I told them what needed replacing; they replied it was not the crankshaft sensor but a wheel sensor. I told them no codes were showing for it to be a wheel sensor but, they insisted that it was. The car was left on their forecourt for 3 days waiting to be repaired. I went back to collect the car and they told me to bring it back when the ESP light showed again they also went onto tell me that the charge for running a scan was 36£ and that they had cancelled the codes. I refused to pay them
and having took the keys off them drove off. Not sure what they intend to do but, I aint afraid of Cowboys.
After driving a couple of mile the ESP light came followed shortly by the engine light. Believing that the research I had done had identified the fault, I ordered a Crankshaft sensor from ebay at 12£. Unfortunately, I could not find this crankshaft sensor. I knew it was near the oil filter but, just couldn't see it. So, I took it to VW Tec. They ran a scan which took seconds; they didn't charge me for this. Consequently, they agreed it was the crankshaft sensor and for some reason it was being read through the ESP sensor. Moreover, they changed the crankshaft sensor which took all of 10 minutes.
The Esp light and Engine light did not reappear. JOB DONE the car is good.
I have been in contact with the VW Owners Forum and related this incident
