Threads with a patronising tone of "I told you so" aren't helpful... Not everyone can follow Uncle Dave's recommended component replacement schedule !

My approach is always be prepared (former Boy Scout) and NEVER be a victim of your own neglect. I carry all the critical spares (and tools) with me when I take the UrS4 on a long trip. No way I am going to be beaten by my own car.

Admittedly, not every one will agree with my approach. However, by making a post that flags the issues, people can read up and decide for themselves. Not having that knowledge and simply relying on the AA (or AAA or CAA or SAAA, etc) road side recovery flatbedding service as the solution to all UrS problems is foolhardy in my opinion, given the age of the vehicle. Even if you get flatbedded to the next shop on your trip, the likelihood that they have the required spares in stock is virtually zero. This will steal days and money from you and your companions while you wait for the parts to arrive.

So bottomline, if you don't plan ahead and do preventative maintenance or bring the necessary spares with you on your UrS trip, at least be good enough to plan to breakdown somewhere exciting.

Based on a recent and yet another "sparkplug blown out of the head" post, I guess I need to bump this on a monthly basis.

Hi Dave,

Even on my 48k miles UrS6.

Number 3.4 on your list got me yesterday on short journey.

Coolant return from turbo - short rubber pipe.

Thought I could smell coolant while driving, then the low coolant warning light came on. Pulled in and had a 2 litre bottle of water in the car so topped up the water bottle which was nearly empty. About a mile of city traffic previously the warning light came on, and could smell the coolant about half a mile before that.

Turned out to be a small 'burst' in the black rubber pipe at the grille end of the pipe. Put a zip tie around the tear, tricky to position especially when the engine is hot, but this has stemmed the leak to acceptable level where the car can still be driven and only lose a small amount of coolant on a 5 mile journey.

Will be / needs to be replaced asap. Have zip ties in your car and rubber gloves.

Going up to the dealer to order the metre of pipe, as can't find any spare in my black hole of a garage. :roll eyes:

Re-read Dave's monthly reminder list and check you are 'OK' / will be 'OK' when it happens. as it will.

:roll eyes:

Thanks Dave.

End of today's blog.

Turbo Coolant and Oil Feed and Return Lines

Sorry to hear that. I will happen to all of us with 3Bs, AANs, ABYs and ADUs. It comes with age not necessarily mileage, as you found out. Either carry the necessary hose with you or pre-emptively replace it before it splits and you lose enough coolant to fry the 20VT head.

Make sure that the N 0202621 hose you get is the one below:

NOTE: Because of the different design of the S2/RS2 (ABY/ADU) water manifold (because of the radiator at the side of the engine, not the front like the AAN), the rubber turbo coolant return hose, while it has the same PN, N 0202621, it is only 73 mm long, not 160 mm like the AAN.

Dealer said it was NLA. Dropped in 2014 without replacement.

Went to the local auto factors and bought Gates fuel line hose in 10mm ID as that's all they had, as a stop gap.

Does anyone have a link to a company that can supply a heavy duty water hose for this 'pipe', as want to be able to fit a decent pipe once and forget about it for a good few years.

Can't find a suitable supplier just yet where I'm based.

Ordered four samples of the pipe below it before they too go NLA.

i.e. the one from the thermostat housing to the water manifold.

Thanks for any suggestions.

Nice. Thanks Mr. Audi.

Some folks have used high-temp silcone hoses for this application. Would NOT be my first choice but in dire circumstances.....

Sorry I hadn't bumped this since May and somebody (John B) succumbed to a blown spark plug.

Not my fault (this is post is in the Guides and Top-tips section) but still...people need reminding.

yep, just checked my compression a couple days ago to find my plugs about hand tight [emoji58]

Well at least the reminder helped you save yourself from a world of hurt due to a sparkplug being blown out of your 20VT head.

**Error404** · 12 December 2015, 17:57

Dave, perhaps add to your guide that plugs should always be torqued when the engine is cold?
