Hello! Would you be so kind as to suggest where I should start looking now?
First, 2-3 years ago my 2004 NA coupe (now at 88k miles) started intermittently stalling while driving/failing to start/combination of both. After doing the research, I had the CPS replaced and that seemed to have fixed the issue.
Last summer, I started having issue with the car failing to start again (turn the key – all dash lights come on, then the fan kicks in but engine won’t start, can’t tell if cranks or not – I believe it’s just silent when I turn the key). I had the battery replaced a month before that so that was ruled out. My local shop cleaned the battery terminals (had some corrosion built up already) and the problem went away until now.
Finally, a week ago the XF failed to start with above mentioned symptoms on several occasions again. Took it to Chrysler dealer (just to make sure) and they could not find anything and, according to them, there were no error codes found. I also had them look at the RCM and they, obviously, they did not find anything wrong. Surprisingly, they did not charge me lol So a few days ago I had my shop clean the terminals again (had very minor corrosion) and had no problems starting the car for a few days until today when the XF stalled at a traffic light and, again, would not start for approximately 10 minutes.
P.S. Every once in a while a check engine light comes on with a P0410 code and goes away after a day or two.
Would you suggest I change out my RCM? Could it cause the car to stall? Or look into CPS again (not sure what brand CPS was put in last time but I believe the shop that installed it got it from benz dealer)?
Thank you very much!
Nik
