Thanks to a member of the site, I was able to carry out a diagnostic check on my car when my engine light came on. These faults were found. Any advice on how these can be sorted please? 17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!) P1297 - 35-10 - - - Intermittent Hope it is nothing serious.... 17545 - Fuel Trim: Bank 1 (Add): System too Rich P1137 - 35-10 - - - Intermittent Is the MAF the main culprit? My temp sensor is buggered so I already I have to change that http://wiki.ross-tech.com/index.php/17545/P1137/004407 01367 - Central Locking Pump Run Time Exceeded (Likely Leak) 35-00 - - Finally, a Haldex communication error. I can not find the code.
