ENGINE BLIP!

Lancerlot · Sep 27, 2022

So, I just had the first hiccup on my MY 2021 Macan GTS. I was out in the wastelands of North Devon doing a spot of reconnoitering for the forthcoming Macan Register Tour.

Pulling out from a minor road into a busier 'A' road, the engine died on me momentarily, then restarted but began to misfire, then died again, picked up momentarily then carried on in limp mode for a while with a yellow engine check light showing up on the dash.

I needed to climb a steepish hill and it seemed to be stuck in 2nd gear with 4k engine revs all the way up. But, on reaching the crest, to my relief the fault suddenly cleared and all returned to normal. Safely home, I went for a cuppa to ease my flagging spirit and on returning to my stricken motor found it fired up immediately, no CEL appeared and it has been performing as it should ever since.

I've no idea what happened, but I did suffer quite a similar situation with my previous Macan SD while driving up to Birmingham on the M5 when the engine suddenly went into limp mode. Luckily, I was only a few miles from a PC and managed to limp there only to find it cleared after being restarted with no fault was found. I was told it was likely to have been a result of regeneration of the particulate filter. The GTS is, of course petrol, not diesel, but petrol engines do have particulate filters too nowadays and I'm wondering if this is a repeat of this. Most of our journeys are of the running short errands around the neighbourhood type and I suppose it's possible filters can become clogged - although still a modest proportion of my motoring is done in 'spirited' fashion. [

] Mileage is quite low for age at only 8k miles.

I had already booked a first service on 9th November, but with 50 odd PCGB members coming down for our Macan Tour at the end of October, I was keen to ensure there'll be no reoccurrence of the problem. Porsche Bristol have been very good in finding me an earlier slot and the car is now to be checked and serviced within next couple of weeks.

That'll be good as I don't really want to suffer some disastrous failure whilst leading a long convoy of Porsche Macans around the lanes of Devon, Cornwall and West Somerset. I'll let you know should any specific fault be found. [8|]

Clive

Anything similar in the Macan`s manual ?

Petrol particle filter[/h2]
Updated 01/08/2018

Petrol cars are fitted with particle filters for more efficient emission control.

Particles in the exhaust gases are collected in the petrol particle filter during normal driving. In normal driving conditions, passive regeneration takes place, which leads to the particles being oxidised and burned away. The filter is emptied in this way.
If the car is driven at low speed or with repeated cold starts in low outside temperature, active regeneration may be necessary. Regeneration of the particulate filter is automatic and normally takes 10-20 minutes. There may be a smell of burning during regeneration.
Use the parking heater in cold weather - the engine then reaches normal operating temperature more quickly.

[h2]When driving short distances at low speeds in a petrol car[/h2]The capacity of the petrol emission control system is affected by how the car is driven. It is important to drive varying distances at different speeds to achieve optimal performance.
Driving short distances at low speeds (or in cold climates) frequently, where the engine does not reach normal operating temperature, can lead to problems that can eventually cause a malfunction and trigger a warning message. If the vehicle is mostly driven in city traffic, it is important to regularly drive at higher speeds to allow the petrol emission control system to regenerate.
