Looks like cleaning helped. Errors gone.

Nice one! Keep an eye on it - but they can get dirt / water inside - unsurprisingly considering how exposed they are!

Well....all came back thisorning....

Ok, so you may well have a loose pin or bad connection in the socket - so looks like you may need to get it replaced after all if the same fault codes are reappearing.

I just hope it is not some damaged wiring somewhere. I am waiting for new sensor to be delivered today. Fingers crossed. I hate to see warning lights on the dash.

Replaced the sensor. Lights still on. Connected DiagBox v7.62. After clearing faults I still have C1391 00...
Engine ECU not recognised. Good few modules were like that. Is this software or I what?

Where did you get your VCI unit from? ECUs not being recognised can be indicative of a non-full chip kit, usually found on the less expensive Lexia kits.

Paid €90. Said full kit. Might be not.....

Sounds around the right price for a full chip - but it can be a bit hit and miss.

Friend at work has Autel tool. Will try that one. Hope it will reset that DPF aditive warning for me.
My Lexia managed to delete all errors from ABS module. I hope it will stay that way.
Maybe you know whitch is the best tool for around €300-€400?

Small update:
Fitted new sensor and erased errors.
Nothing pops after engine start. Now I have ABS /ESR error after some driving. Sometimes few miles and sometimes 15-20 min. Errors appear in two stages. Abs/Esr and after some time Tyre pressure, Handbrake, Hill assist etc.. After 2nd batch of errors appers, GPS frozes.

Looks like damaged wire....
What is the way to troubleshoot this? Check continuity? Is wire from ABS rear sensor goes directlyto ECU?

Hi Marc,

sorry for disturbing you....
Could you help me with my ABS issue. I want to check continuity of rear right ABS sensor. Does the wires from sensor go to ABS ecu? If yes, what pins. Thank you.
