Hello! Driving to work this morning I noticed the car seemed a little off. Maybe a slight judder here and there and when I checked the driving data my mpg was poor. 33mpg where I would usually always get 40MPG on my commute. Popped the hood when got to work and got a slight burning smell but couldn’t see anything wrong. Scanned it in car park after work and no codes on OBDeleven. Hmm :huh: on the way home mpg was again bad and car just feels off. Slight bad smell coming though the vents when I stopped at junctions etc. anyone any ideas??. I’m on original coil packs but did change spark plugs once.

GPF cleaning cycle, 4th post down??

Nah it’s a 2013 gti. It doesn’t have a GPF
-
The current cold weather will have an adverse effect on mpg.
-
Not that much. I’ve had the car since new and I know when it’s not right. And it’s not right
-
As it's been mapped to stage1, would the ECU still detect a catalytic converter fault?
I'm wondering if it's partially blocked or breaking up.
-
I would try a scan with VCDS if possible??
Perhaps look at the data for the lambda sensors.

Update. I took off the coil packs(nightmare as they were welded onto the plugs) and pulled the plugs. All looked ok so I replaced. Took it out then for a hard spin, seemed ok for first 5 mins then got bad smell again and the stuttering was then felt again, particularly under braking. When I got back to the garage the drivers side front brakes were billowing smoke. The alloy itself was red hot. Front brakes and pads (Brembo) were professionally fitted about 3,000km ago and are as new. I assume the calliper or something is causing the brakes to stick. This would also explain the poor mpg on my commute this morning. Any ideas on how to approach this? The passenger side and rear brakes are fine and cool. And yes the slider pins were lubed up when fitted.
Thanks for the replies so far. Brakes aren’t my strong point :embarrassed:

Sounds like the piston is seized in the caliper or maybe the pads are seized in the carriers.
Piston and seal kits are available I would imagine from TPS or somewhere like this https://www.brakecalipersolutions.co.uk/product/fit-vw-golf-mk7-2012-2014-front-axle-brake-caliper-seal-repair-kit-bsk5747/
Just depends on what the pistons like, if the chrome has started to peel they're knacked.
Normally what I find is that someone has torn/ripped the dust seal which allows water ingress which then creates rust on the lip between the actual fluid seal and dust seal causing the piston to stick.
If your not confident in working on your calipers though, best leave it to someone who does.
Or just get yours remanufactured, and in a choice of colour too. https://www.biggred.co.uk/caliper

Thanks Madstaff. Have it booked in to my mechanic to confirm the Caliper is the problem. He did say it’s rare for them to fail, especially in the fronts. Will post back when diagnosed/sorted.

The golfs and Audis have always had problems with brake calibers seizing, you're probably better off with it being the front as the rears are more expensive due to the e-brake.
A caliper repair kit is about £14, from big red. Also I think Mastiff linked you to the standard Gti brakes not the Performance pack ones on the CS's. Which you'd probably find hard to get but here's golf R ones below:

Will, I think you have assumed CarbonVW has a Clubsport due to his signature, as I did.
But I think in fact he has a 2013 Carbon Steel Grey Golf GTI.

Ahhh my mistake, although not a bad time for an upgrade :wink:

Don’t tempt me even though I’m tied up for a while just bought a 2020G31 530d to keep the miles down on the GTi

Update, ripped the caliper last night and popped out the piston and it was badle corroded on the lip and the chrome damaged. I cleaned it all up as good as I could with different water based sandpapers and my mini rotary tool. The sliders pins were free and perfect. All the rubber seals were in good condition. Covered the piston in rubber grease, refitted everything and it was instantly better. Bled the brakes and test drove it,all ok. Will see how long that lasts but have ordered 2 new genuine TRW callipers from this German website which were a great price for the full assembly. Price is ex vat and delivery.

You just triggered my PTSD. I pulled my 4 coil packs out the other week. I don't have any tools so pulled them out by hand, just had to constantly pull with brute force gritting my teeth together until I had them all out :undecided:
