Hi guys,

Been a minute, hope everyone's well. The time has come to make a decision, and I need some advice.

I've had a wonderful year with Jim the FSI, but we've had some bad luck - the brake servo is malfunctioning. It's been nearly 3 weeks since he's been off the road with this issue, and I've since contacted about a dozen garages around me - most of them VAG specialists - but no one will touch it. I understand it isn't a common, easy or cheap task, but literally every single garage has turned me down. I need the car to commute to work, so this has been extremely frustrating.

I have a mechanic friend who will possibly (and reluctantly) do the job for some good money, but then again, this is putting a lot on a friend I'd like to keep happy.

So, the question has come - is it worth carrying on to find someone to do the job for a large sum (probably around £500 all in) or do I just sell Jim as-is? I reckon I could get around a grand more once the work is done, but is it worth the time and trouble?

Any thoughts would be brilliant. If you have any local heroes (I'm in Rotherham, so the furthest I can take the car is around Sheffield, Doncaster, Barnsley kind of areas) then that would be great, but again I'm looking for opinions on whether this is worth the effort.

Thanks everyone.

Can you describe the symptoms, or any details that point to the actual servo itself, rather than the hydraulics attached to it?
Mac.
 
Good point Steve,

According to Dr. Goog;le Sheffield is only 47.2 miles to Stoke on Trent where WOM Automotive reside. Mac could well have more ideas, being an aknowledged luminary on matters FSi. The important thing to remember is that these cars are a bit allergic to mechanics who do not understand them fully.

Best of luck.

VERY vague statement. What is the issue and any unusual noises. The hydraulic side could be the issue or the vacuum side. Although the garages have turned down the job have any confirmed the issue or even looked to see the issue? Has the car been correctly serviced and the fluids changed on time?
 
Hi,

I have never had an issue with the servo and I cannot comment on this. From previous knowledge on other makes, it might just be a simple non-return valve and a length of hose. In all honesty these don't go bad that often unless they have corroded entirely.

In any case, if you decide to sell it on or break it, I would be interested in the engine please. Depending on mileage/servicing/etc.

Evros
 
Hi everyone,

Thanks for the replies. I was coming back from Liverpool and my brake pedal started hissing at me. It gradually got louder and when I arrived home the idle was extremely lumpy. I sent it to my mechanic friend's place and they checked all the surrounding hoses, finding no leaks, leading us to believe that it's the servo itself that is causing the vacuum leak.

This is all I know, however, last night my barber visited and rang a friend whom owns a German specialist garage. He stated that it could be corrosion on the servo, or I could try a smoke test to see where the leak is coming from, as it could potentially just be a valve issue. Unfortunately his work partner is going for surgery for the next 6 weeks and he wouldn't like to attempt it without him. My barber did give me another number, though, so I'm trying him this afternoon.

I've thought about WOM as I'm aware of their expertise and favour on the forum, but I don't think the car will do that far of a trip. At least, I don't want to risk causing more damage to the car by going that far. But if I was closer it would be perfect, I appreciate the advice a lot.

Thanks,

Are there any dash warning lights on?
Mac.
 
Just an update on the current situation:

Managed to get a hold of a couple nice guys at Autotecnics near me. They can't do the job on the car because one of the guys is going for an operation and is needed for it, but they took it in to have a look and give us some advice.

They said yes, it's definitely the servo that's gone. They checked in and around the area, as well as doing a smoke test, and there's a definite corrosion/leaking issue with the unit itself. No dash lights on for anything during drives and has actually been driving slightly better since my mate resealed all the hoses. Hopefully this has extended the range it can go for some work.

So, progress, but no solutions. I come to ask; does anyone know the part number for the brake servo or where I can find it without lying on the street with a torch in my mouth?

Many thanks,
-Saff

You'd be there a long time, waiting for an FSI to come along, I reckon
Mac🤔.
 
Try looking here, pricey though

If there's an air leak, it's possible that the leak could be coming from the "servo" or the "vacuum pipe with non-return valve".

Earlier type of servo for RHD all engine versions (MK20 RHD servo) 8Z2614206
up to VIN 8Z-2-013 000
Later type of servo for RHD all engine versions (MK60 RHD servo) 8Z2614106
from VIN 8Z-2-013 001

The MK20 RHD servo is matched to an MK20 master cylinder.

The MK60 RHD servo is matched to an MK60 master cylinder.

The below parts diagram shows that there are six different "vacuum pipes with non-return valves" labelled 1, 2, 3, 4, 3A, 4A. The RHD 1.6 FSI uses "vacuum pipe with non-return valve" numbered 4A.

Earlier type of "vacuum pipe with non-return valve" for RHD 1.6 FSI (8Z2611931G
up to VIN 8Z-3-050 000
Later type of "vacuum pipe with non-return valve" for RHD 1.6 FSI 8Z2611931M
from VIN 8Z-4-000 001

It appears that 8Z2611931G and 8Z2611931M are interchangeable, so you could use either on a RHD 1.6 FSI.
