First and foremost thanks for adding me to the forum.

Sunday morning my daughter told me she hit a pothole driving her 2012 Eos. She said it was the passenger front tire.She said afterwards she could hear a rattle from underneath. I decided to take the car for a drive. I started it up and noticed the CEL lit up. I picked her up Friday for spring break and she drove home. The light wasn’t on then.
Anyway as the title says, it’s the intake manifold sensor. I read about it on some other threads here. My question is could something have come loose as a result of her hitting the pothole? Or is this simply coincidental?
Btw, the rattle appears to be from a loosened bolt. I think she broke the plastic cover underneath in front of the front passenger wheel.
Thanks

Doubtful, the CEL has probably been on for a long time. At least it wasn't the low oil indicator that was ignored.

Did you not read my post? It hasn’t been on. On Friday I drove it to Pittsburgh and we drove back. No CEL. Thanks for your “input”

My gut reaction tells me that the CEL would coincidental to the pothole strike. Most of the engine sensors are up and in so to speak from the suspension components. A hard shock might have knocked something loose, but I’d expect a lot more in terms of a suspension issue if that were the case. Fortunately the EOS has a fairly common VW engine as others have found the manifold sensor fault isn’t a rare/unheard of problem. So in the hands of a competent VW mechanic, I would expect this to be an easy fix either with a new manifold, sensor or both.

Speaking of suspension…. A front end inspection/alignment is probably in order as is the repair of whatever is loose. I’m guessing you may have thought of that already.

Drop the attitude, its not welcome here.

Some faults are logged in the ECU which determines severity from number of events, time and distance travelled before a dash warning is given. Therefore your cause and effect conclusion are probably wrong. The next event could be limp home mode? Decent diagnostics will show time and date for each fault event logged. But I guess you only have a basic fault reader and not a mechanics tool to do mechanics diagnostic work?

Ok, you first.

I did. The strange part is that the alignment doesn’t appear to be off. No pulling, no vibration. More than likely a coincidence. But I figured I would ask here.

It sounds like a good VW specific diagnostic read is in order (if it hasn't been done already.) The codes rendered by a VW specific scan may give you more granularity as to the problem. I'm confident a dealership could sort the CEL issue, but that's expensive, so the logical alternative would be a good VW mechanic. I'm sure if you check locally one will turn up, but the usual advice here is to avoid the national chain shops and find a good independent garage that caters to VWs, Audis, and such. Keep us updated on what you find out.

Thanks I’ll take it to a dealership next week. It doesn’t get driven much with my daughter being at college.

Front or rear misalignment is a common problem when cars hit obstacles, kerbs or potholes. You don't always feel anything, but will feel the cost if tires start wearing unevenly. I wouldn't trust a driving opinion to tell me if there was suspension or steering system damage. I would rely on an expert inspection and a 4 wheel laser alignment check if I wanted confirmation the car was safe to drive and wouldn't wear out tires. Broken front springs are common on modern cars on bad roads and you don't always see that looking at the wheel arch height.

Thanks for the tip. I’ll have them check the alignment when I get the cel diagnosed

Well the car is at the dealership. No damage from the pothole. An alignment is being done. They recommend replacing the intake manifold. Due to the CEL. I’m getting that done along with the timing chain replaced all at 106,000 miles.
