I bought a 2006 bmw x5 with some issues main one being the transmission failsafe program. The guy I got it from said it didn't do it to him till he changed the calipers. But I have changed the battery the alternator and it's still doing the same thing what else can I look at. Here are the codes my scanner gave me

P17f6

P17e1

I am at a loss

Hi Michael

Welcome to the Forum

My guess is whoever you brought the car from has seen this and it scared him into selling (hope it was cheap)

How does the car drive ? are changes smooth without the fault? Or is performance restricted (normally car stuck in 3rd gear)

The problem could be seals in the mechatronic unit or with the Sleeve gasket where the EGS connects to the box.

I would try the simple things first, service the transmission. A Fluid and Filter change and a new sleeve gasket (make sure the Fluid is correct for your box) "Tip" if you are going to service the box make sure you can remove the fill plug first seen a couple that were stuck because they drained the trans then couldn't get the fill plug out. If a fluid service cures it Happy Days if not then it could be an EGS problem or at worst a Trans rebuild

Fingers Crossed it is the simple fix

Grey dog it seems like it is stuck in a higher gear will move but only at like 2000-3000 rpm

Morning Michael

Not good news and that has been going on for some time I would say so the seller wasn't truthful

Check the Transmission for any sign of leaks especially around the Mechatronic Plug it may be worth carrying out a Service (Change fluid and Filters) see if that cures that issue. Your car was built in a time when BMW were saying Transmission was sealed for life !!! What they meant was sealed for the length of their Warranty responsibility (60k miles) ZF who manufacture your gearbox recommend service between 60k and 100k km dependent on use and climate

Unfortunately if a service doesn't do it then the box will need a rebuild or changing, that wont be cheap either way I would expect a Specialist to charge around £2k + may be as much as £3k to fix it

Good Luck
