Hi Folks -- I've been away for a while which I suppose is a good thing (it means the car is running, right?), but apparently the W210 misses you all.
On the way to the autoglass place for a windshield (ironically the first thing we've had to fix in at least a year), the check engine light popped on just after my wife was starting the car. I've trained her well. She turned it off, called the autoglass place to cancel, then called me and told me to fix her car. I drove the car previously -- two night earlier -- No CEL and it ran great. It was below freezing, but she said the car started immediately. When the CEL didn't go away after a minute so she shut it down. I started it later, again fine, then checked codes with the OBD code. The only one showing (nothing pending) was P0335. I cleared the code and started the car a couple times -- it didn't come back or show as pending.
I know these CPS fail all the time, and I've been meaning to replace it anyway, but I do think it's odd that we have none of the usual symptoms that many people experience (stalling on freeway, no-start), meanwhile we do have the code but no symptoms. Maybe I should count my blessings that this is happening in the driveway, but still, it's weird. Any thoughts on it (weather related?), or should I save the speculation for grander topics and fix the damn thing?
I know this CPS comes in two versions, and I know I can go pull the connector and make sure I'm getting the right on BUT, it's snowing. And cold. So I'm hoping to do this with part numbers and the internet.
Here's the CPS I'm thinking of getting (mostly because the price is decent and Amazon will deliver it same day:
My engine (according to data I pulled and saved from the RU EPC before they killed it) is: 112941 31 042292, which I think is reads as 31 042292. And since 31 is greater than the 30 their number starts with, I should be good to go. Right?
I also just found out that in my absence, my MBUSA EPC expired in Sept and Mercedes has since killed free EPC access. Bummer. If anyone still has access and can double check online, my vin is: WDBJH82J21X061262
Thanks in advance!
