I thought that there was perhaps a sensor in the wheel arch that I had damaged with the power wash, but probably just a coincidence, tried disconnecting the battery light comes back on within seconds...

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

2009. Power Washed the car at the weekend,about 200yds later PTM failure and PSM failure lights came on.. drove on hoping it was one of those occasions where the warning light goes away, unfortunatly not. I was paying particular attention to cleaning the rear wheels/arch and am wondering if I have damaged a sensor or something..... Anyone experienced similar or have any obvious home remedies to try before seeking further help? Thanks.

POST 2Original post

Is it on permanently? I know it's common for those lights to come on with a faulty MAF but in that case it's usually only once the car's accelerated.

POST 3 / ORIGINAL POSTEROriginal post

thegoose said: Is it on permanently? I know it's common for those lights to come on with a faulty MAF but in that case it's usually only once the car's accelerated. No its on all the time. Cant activate the sport mode(overboost etc) however can harden the suspension.. I thought that there was perhaps a sensor in the wheel arch that I had damaged with the power wash, but probably just a coincidence, tried disconnecting the battery light comes back on within seconds...

POST 4Original post

Hi - any update here, did you manage to resolve this as I am having similar issue. Drove through torrential downpour on motorway - now have a number of issues - rear lights / reversing lights - warning coming up - but all working - rear spoiler no longer works - rear engine lid won’t release - front trunk release doesn’t work (but key fob works) Also had a moment driving along where hazard lights + interior lights came on L plugged in computer to check errors codes but nothing coming up that we can clear Any help appreciated (I’m 250 miles from home !) Tx

^ What car? that sounds like symptoms typical of water ingress flooding the below driver seat and passenger seat ECUs. Would tally with driving through torrential rain Have you checked for wetness below the seats?
