[E9xrob]

Hi all,

I’m looking for some advice and explanation please!

I have a 2007 E92 325i. I bought it with low miles that all seemed legit from the service book, MOT history etc. it did have the tamper light on so I got it checked by a guy with a decent code reader.
His findings were that the CAS module had a different mileage and VIN than the car and DME. Explained the tamper light at least.

It was always a job to do at some point to look closer into the need to get the CAS in virgin state and coded to the car so my tamper light goes.

The car developed a fault and I ended up not using it for a few months and just used the E91 instead. I started and ran the E92 a fair bit and all was fine but then I left it for about 7 weeks without starting or running. I started it the other day and the cluster where the mileage is started at 45xxx as expected and then within a split second flashed off and back on to 125k.

My understanding is that the CAS coding is what is needed so I am hoping someone can help confirm and advise who is best to help?
Also, why would a low battery cause this to happen? I’m confused.

Thanks everyone in advance for any help!
