How to Guides / Troubleshooting / Fault Code 01810 - not getting hot air on drivers side

« Last post by aweds on Today at 08:10:02 am »

Symptoms are that I am not getting hot air in the drivers side (right hand drive) and diagnostics is showing an intermittent fault 01810.

From research I am going to replace the Postioning Motor V159 but I can’t find any instructions on how to reach it from a right hand drive car.

Any advice greatly appreciated! It’s at this time of year you realise how much hot air on the windscreen helps!

As well as the above, the intake valves/ports can get gummed up with carbon due to the direct injection set up.

Injectors are a weak point causing misfires

I had an Edition 30 until 4 years ago, I also had issues with:
passenger door lock
ABS sensors and hubs (rear)
Intercooler hose fitting, required new hose
coil packs and plugs after remap.

Great cars though especially with a map to give over 300hp (Edition 30)

A recent post has reminded me to pay attention to rust on sills and wings, also tailgate!

A few things to be aware of:

Check cam follower condition - this is a replaceable tappet that runs the high pressure fuel pump via the inlet cam lobe - they can wear through and damage the cam and HPFP if not properly maintained.

Inter-cam chain and tensioner (in particular) can wear and need to be inspected regularly after 100k miles or if noisy and replaced.

Diverter valve diaphragm often split causing boost issues.

Also PCV valves fail as well as old hoses, cheap to replace though

Some GTIs do consume some oil.  Later models are better from my research and in particular the Edition30 model, which I own, rarely has oil consumption issues.  I use 5w40 oil and it doesn't use a drop between oil changes

Top mounts on mk5 Golfs are horribly designed and if they've not been replaced in 15 to 20 years they are a nightmare to get off if needing to replace the suspension.  The 3 captive nuts on each side can become "uncaptive" and spin freely, meaning you cant get the damn things off and have to cut the nuts off in limited space underneath, or from the bolt at the top (not something I'd enjoy repeating)

I'm sure others will chime in with additional niggles, but those are most of the ones I've kept an eye on in my ownership.

If you find yourself with the budget to stretch a bit further, I'd recommend the Edition30 BYD engined GTI, much more potential out of the box and uprated in quite a few areas compared to the standard GTI engine.  I am considering selling mine in the near future as I want to move back to a VR6, in case you're interested!

Mk5 General Area / Known Issues

« Last post by JW on Yesterday at 11:48:49 am »

New member, so hello to all.

Very likely to be getting into a Mk5 GTi very soon and wondered if there are any known issues with these?

I was a long-time Mk4 owner (sadly had to sell due to ULEZ) and have had lots of VAG group cars.

I know that at a certain point VAG forgot how to make engines for a while - VW and Audi both had issues with timing chains/tensioners and piston rings/oil consumption, etc.

Just wanted to check there's nothing inherently silly like those on a Mk5 GTi... Are these timing belt with just a chain for the cams, as on the Mk4 1.8T? Any oil consumption/piston ring issues to watch out for?

And just anything else I should be looking for, or wary of, on these models in particular?

Any advice or experience would be greatly appreciated

Had this on mine last year. Think you're right about the mecatronics.
I ended up selling my car as I'm no good with the spanners.
I'll try and find my old thread and link it.

Mk5 General Area / PRNDS Flashing Issue on my Golf GTI Mk5

PRNDS Flashing Issue on my Golf GTI Mk5

Hey everyone, hoping someone might have some advice.

Got in my car earlier and it wouldn’t start at first, but after a few tries it did. When it started, I couldn’t get it into gear at all. I used the manual shift unlock to move it into drive, but the car still wouldn’t move and the PRNDS lights started flashing on the dash.

It’s a 2006 Golf GTI DSG with just over 180,000 miles. Has anyone had this happen before? Do you think it could be the mechatronic unit or something simple like the brake switch?

Any advice or recommendations for decent gearbox or DSG specialists around St Albans England would be much appreciated. Thanks everyone!

Ordered a replacement interior passenger door grab handle, and to my surprise the GTI now has parts classified as classic  so a longer waiting time with some mk5 parts now
