VW golf 1.6 16v AZD issues

[dp99]

Hi all, I have been having several problems with a golf of mine. I bought it with the head gasket gone and after rebuilding the head I have no end of idling problems. Numerous fault codes came up to begin with, started with replacing all the coil packs this made it run a lot better. Then cleaned throttle body and replaced lambda sensor, this helped further and got it to run up to operating temperature 90 degree. Once it hit 90 degrees though the engine management light came on along with the EPC light. Replaced EGR valve, adapted throttle body and MAP sensor, and no change. The idle is a little unsteady, but hits 90 degrees, throws up the EPC light and eventually starts to hunt and then goes into limp mode and wont rev up at all. If you shut the engine off it wont restart until it cools down again. But when it does cool down starts and runs fine until it hits 90 degrees. When the EPC light comes on I get the fault code 17961 - P1553. Any one got any ideas???

If you google that fault code 17961 - P1553 there are loads of results/ forum discussions which could lead you to a fix, but could equally lead you in the wrong direction. There is no difinative answer.

It might be more viable to take it to a specialist garage than spend money on parts guessing.
