S60 D5 185 - Flat Spots, Limp Mode - Intercooler Bowed?

JTSD5 · Feb 11th, 2022, 14:29

Hi

Last few days I've noticed flat spots in power, around 2.5-3k rpm. Then last night 'Engine System Service Required' popped up and car went into Limp mode. Got home and had a look around and noticed the plug on top of boost solenoid had come loose, plugged it back in, no Limp mode but still flat spots and System Service. Driving today at around 70mph, 'Soot Filter Full' came up and back into Limp mode.. Drove around 20 miles home in 4th gear to see if it would clear, would seem to clear up at get to around 80mph then bog again. Got home, turned it off and on again, no Soot Filter warning, back to how it was with flat spots..

Checked all vac pipes and hoses to IC & Turbo, all seem good. But then took the undertrays off and noticed how much the bottom of the IC is bowing down, with oil either end of it.. Before taking the whole lot off and replacing IC just wanted some hopeful confirmation that it is definitely the culprit?

I have noticed it is smoking slightly at idle lately, but never seen any whilst driving coming out the back.

I drive long journeys and it isn't exactly driven slowly, so can't imagine it would be DPF? .. Fuel Filter, EGR, Turbo?

Not sure if the links will work or not..

Almost definitely intercooler, it'll be leaking air so the engine is running rich. Due to the dpf filter you don't get the traditional smoky exhaust, but a clogged filter instead. Get a pattern one from eBay, just check if you have a sensor plugged in on the top left as you look down while standing at the front of the car. There's two types used for the d5, one with a sensor, one without.

Brilliant, cheers mate. Now off into the garage to start stripping it down! The joys of bangernomics!

New IC fitted, EGR cleaned, New Air & Fuel filter and she's like a new car!.. Amazing how you don't really notice gradual changes over time.

Now, could someone please tell me how to clear the 'Engine System Service Required' ? I've tried holding the mileage reset and turning ignition on, the warning triangle flashes but there is no noise, tried every technique I can think of but can't get get rid of it..?

Cheers

should be one of these methods unless I've misunderstood what you're after exactly

Cheers, although I've tried all them.. I'm guessing the normal 'Service Schedule' is different to 'System Service' ?

Clearing stored codes will clear the Engine System Service Required message. Vida or iCarsoft.

Might clear itself after some driving without faults.
