Hi everyone,

 

We've got our 1.2TSI 2017 Yeti in for it's major service. The oil plug thread has stripped when being removed from the sump. The garage has plugged it temporarily but they are not sure how well it will hold. I'm being told we need a new sump at a cost of £820.

 

Anyone had this? Any cheaper ways to sort?

Many thanks in advance,

Ben

Ben, you don't mention where you are, but if in the UK,

look up Sump Pan on ebay. Type in the car details.

Or try here first.

Don't forget to give them a call to make sure you get the right part.

 

Looks like there could be either Metal or Ally sumps.

Add more information

Hi, thanks. I'm in Sheffield. They seem to be less than £100 on Ebay, though it's not something I'd fancy sorting myself.

If the garage stripped the thread then they should be paying for it, not you!

Difficult to strip a thread when removing, far more likely it was damaged by someone who had it out in the past cross threading on the way back in.

£820 for a sump is pi55 take surely!

 

Steel or alloy can't see why an in situ Helicoil repair wouldn't work, certainly worth a look as it would cost very little.

 

Is that the main dealer there who wants big money ?

Always possible to Plug it permanently and just suck out oil from now on at oil changes.  (Kerbside Auto Solutions.)

Hi everyone,

Thanks for the replies. Yes it's the main dealer. The thread pulled out with the plug, so it wasn't cross threaded. Not unheard of on a Yeti apparently.

Could helicore but only a temp solution apparently.

Will shop around...

This section has gone a long time.

Not unheard of, but that is with any car, being a Yeti has nothing to do with it. The 1.2 TSI being common across so many VW Group vehicles. 

I always find it astonishing that anyone can strip a sump plug, but what's done is done. 

 

I don't see why a helicoil should not be a permanent repair, especially given the low stress on the component. In some industries tapped holes in castings are helicoiled from new for extra strength. It's a proper engineering solution and by no means just a quick fix.

 

An alternative would be to get the sump casting tapped oversize and have a larger standard or custom made plug fitted by an engineering shop.

 

Main dealers are often pretty hopeless at thinking of cheaper alternatives, they are too tied into simple part swapping.

Sorry to disagree here Graham. 

 

If you are the unlucky mechanic doing the job and its failed on you, no matter how careful you are, it still happens.

I personally have used them many times in the past.

Also a Helicoil is not a temp solution.  If used & installed properly they can outlast the life of the car.

Now, if it was over tightened by the last guy doing the oil change, the next guy to do it, will have no idea until he does it.

Thanks everyone for the feedback. I'll ask around regarding a helicoil repair - the main dealer won't do it as they say they won't be able to provide the 2-year warranty on the work.

If it is holding oil now then take the car to someone that will do the helicoil or change the sump at less than £100 odd an hour plus VAT. 

I am shocked that a dealer would lose their profit margin by removing the undertray and draining the oil via the sump plug when AFAIK 100% of them vacuum out the oil via the dipstick hole.

 

A service by a main dealer does not even have the car on a ramp.

 

Something fishy here but thats nothing new regarding the main dealers.

A helicoil is a common and permanent repair for damaged sump plugs, and whilst it can happen on any car it isn't something I have seen reported on a Yeti here previously.

Personally I'd find a better garage!

Probably the same sort of person who so overtightens an oil filter that you have to virtually destroy it to get it off.

 

My rule of thumb which had served me through countless filter changes on innumerable vehicles:

 

If you need any sort of tool to take a filter off that means it was overtightened when it was fitted!

Helicoil can last a very long time, the sump plug on my 1983 Metro was helicoiled in the late 1990s it’s still doing its job today and oil tight. Just don’t over tighten.
