Hi, recently my ecu in golf mk5 2.0 tdi (140bhp) packing in completely, I was having to sit and turn ignition on and of for ages until coil light came on them would start, however ecu finally died so bought second hand one off eBay and got it decoded..... however engine wasn’t running properly but still had power steering etc.

Then bought an ecu set eg speedo cluster, key with chip, relay board, can bud module and ecu all coded together. Put all items in and engine runs sweet!

This time no power steering what so ever and light is on and steering angle sensor reads 0 to -49 so is getting readings. Says no angle stop tho but would expect that as no power steering.

Also have airbag light on it’s the squab in drivers seat

Abs traction control lights on says rear right speed sensor

Brake fluid light warning light but brake fluid is full.

Someone has coded all sensors with Delphi system since but still no joy.

At my witts end with this now chucked far too much cash at it can someone with the knows please help me even if I could get power steering back for time being I will be happy
