Parktronics problems

[trevor1946]

I bought an ML320 in 07 and had 2 or 3 sensors replaced under warranty. Just out of warranty another 2 failed costing me around £360 to replace. A year ago it failed again intermittently and the Merc dealer said 2 more had failed. I didn't get it fixed and it worked for a while and then died. I decided I wasn;t going to keep spending money on something that wasn't essential. Anyway the dealer did my MOT a few weeks ago (passed) and said I've got two sensors gone (i Know) and Mercedes would pay half the costs .ie cost to me £180. Thought ok would be nice to have them back. Been in garage this week - they call me to say a another has failed. After 3 days in garage they call me to say all is good. Pick it up today immediately not working. They say another one has gone and say there is a scratch on the sensor - barely noticeable
Does any one know whats going on here? 9 sensors replaced in 4 years!!!!

Sounds like they have some sh*t techies in their!!

I wouldn't be too angry with them, but tell them you are frustrated now, and the problem has gone too far, tell them how this issue started when the car was in warranty, and now you are having to pay out of your own pocket!

It may even be worth emailing MB head office? Give the dealer another try first..

All The Best
