Engine warning lights keep appearing
Posted: Wed Jul 25, 2018 1:02 pm
Really sorry to post such a long message on here, but hopefully someone out there might be able to help me.
About 18 months ago the ECU in my VW polo 2010 1.2 completely blew, so an auto electrician replaced it with a 2nd hand one. The car seem to run ok for a few months then one day the Tyre pressure warning light came up on the dash board (this model doesn’t even have the tyre pressure feature) . This light resulted in sending the car into limp mode when it struggles for power etc. Whilst driving round it then triggered the ECU warning light. I was able to clear the fault with an OBD reader after a number of attempts. This repeated itself about 2 months later, so I took it back to auto electricians who told me it was the lambda sensor, which they replaced. The car was fine for about 2 months then exactly the same sequence of events happened. Tyre light comes on, limp mode activated, then the ECU light come on a day or so later, again I managed to clear it with my OBD reader after a number of attempts. This seems to happen every couple of months and after I reset the lights the car runs absolutely fine. This latest time I took it back to the auto electrician who are now saying I need to replace the crank shaft sensor and make sure the timing belt is lined up correctly. So as you can imagine I am a little sceptical that this will solve the problem and just keep costing me money.
Can anyone shed any light on what might be happening here???
For info the OBD reader generally reads code 0322 but sometimes quotes other codes depending on how long the lights have been on.
Any help would be greatly appreciated
