2015 Volkswagen Golf — dPF regenerations seem much more frequent — Salt Lake City owner

CityLearner884Community StarterNov 2, 20252015 Volkswagen Golf TDISalt Lake City
The truck has been doing more short trips and active regeneration seems to happen more often. No codes. What scan data helps confirm soot load and regen frequency before assuming failure?

This is a climate question as much as a tire question. If Salt Lake City only sees a few real storms, a good all-weather on the 2015 Volkswagen Golf can be the saner daily. That's where I'd start. No need to make it theatrical. Not driving it hard until I know more.

This is a climate question as much as a tire question. In Salt Lake City, dedicated winters on the 2015 Volkswagen Golf paid off more than I expected on ice, even on plowed roads. That's where I'd start. On “dpf regenerations seem much more frequent —,” that was the fork that mattered for me. Stop there until you know. Only after sitting overnight so far.

Useful. I'll report back after I verify that on my 2015 Volkswagen Golf. If this is nothing, great. I want that in data.

I'd push back a little: If Salt Lake City only sees a few real storms, a good all-weather on the 2015 Volkswagen Golf can be the saner daily. That's where I'd start. That's the whole play. Video is ugly but it shows the hesitation.

Asking because it changes the advice: If Salt Lake City only sees a few real storms, a good all-weather on the 2015 Volkswagen Golf can be the saner daily. I'd do that before spending real money. Had a similar mess a couple years ago and that's what finally sorted it. Make the next action something you can finish this week. Next check is the cheap one I can do in a driveway.

Agree — and I'd add this: Watch brake clearance and overall diameter if you downsize winter wheels on the 2015 Volkswagen Golf. Then you'll know the next fork. That's the sequence I'd use. Not driving it hard until I know more.

I'd do that before spending real money. A shop burned me once by skipping that step. Doing the boring step first on purpose.

I'll update if anything new shows up.

I'd rather pay for diagnosis than a second guess-repair.

Salt and cold mornings punish cheap shortcuts. Watch brake clearance and overall diameter if you downsize winter wheels on the 2015 Volkswagen Golf. I'd do that before spending real money. On “dpf regenerations seem much more frequent —,” that was the fork that mattered for me. This is from a 2015 Volkswagen Golf in Salt Lake City. Not gospel, but it saved me a headache. This is the version I'd tell a friend.

Fair point. Counterpoint: If Salt Lake City only sees a few real storms, a good all-weather on the 2015 Volkswagen Golf can be the saner daily. That's where I'd start. This is from a 2015 Volkswagen Golf in Salt Lake City. That's the whole play. This is the version I'd tell a friend.

Thanks — that narrowed it. I'm going to try the simpler check on the 2015 Volkswagen Golf first. Cold start is when I can actually reproduce it.

I parked the 2015 Volkswagen Golf and wrote down what I already tested so I'm not repeating myself. Trying not to diagnose from the couch.

Yes, with one caveat: Watch brake clearance and overall diameter if you downsize winter wheels on the 2015 Volkswagen Golf. That's where I'd start. Verbal 'we'll take care of it' is not a plan. Next check is the cheap one I can do in a driveway.

I'd pick the setup I'll actually live with in slush. If Salt Lake City only sees a few real storms, a good all-weather on the 2015 Volkswagen Golf can be the saner daily. That's where I'd start. If they can't show the line item, I assume it's hiding. A day of patience here is cheaper than a wrong part. I already checked the easy fluid levels.

Keep sale price, fees, and rate as three different conversations. Trying not to diagnose from the couch.

I hear you, though I'd still want a second check. Watch brake clearance and overall diameter if you downsize winter wheels on the 2015 Volkswagen Golf. Then you'll know the next fork. Learned this the expensive way on a previous car. I'd rather be boring and correct. If this is nothing, great. I want that in data.
