:lol: 'Scuse me while I change my undies, I seem to have wet meself laffing ...

This is the same VAG who designed the oil filter housing location so that when you remove the filter you puke old oil straight into the alternator and either reduce its life span and efficiency or worst-case-scenario bugger the alternator completely.

This is the same VAG who use more bolts to hold the engine undertray onto a vehicle than to hold the seats in place.

This is the same VAG who design the rear disc brakes (on a Golf, for example) so that the discs and brake pads can't be seen and assessed from underneath the vehicle by an MoT Tester because they are tucked up out of the way and covered with a very close fitting crud shield.

To be fair to VAG they are not the only manufacturer with form for producing complete and utter expletive from a service and MoT point of view, all the others are equally as guilty in some way.

I think I need a lie down :cry:

My Toyota doesn't have to worry about belt change intervals. It has a chain. :D

Point of order M'Lud - I believe the Toyota 1.8 VVTI lump, as found in Avensis for example, is listed by Toyota as being ready for a new chain at around 100k miles. Which means I now need to check my own Avensis. Ahem :oops:

So to complete the story, turns out the particular engine on my Polo (1.4TSi 150bhp Bluemotion) has an electronic water pump not driven by the cambelt. It's actually on the opposite side of the engine.

So the "independent VW specialist" price for the job is actually only £30 less than the VW main dealer, for a £500 job.

Hi,

My Fiesta went the other way. Fiesta had a noisy water pump and deteriorating belt. I had the cambelt replaced at the same time as once the bits are off the front of the engine it's an easy job, rather than having to take the front off again.

Cheers,
Ray.

Ouch. :( Sometimes I long for the days when a Polo was a basic little thing, 50 or 60 bhp but rock solid and cheap to run. The kind of thing you could buy as first cars for your daughters, knowing that you could sleep at night.

An electronic water pump? Even assuming you meant electric, whatever next? Wifi windscreen wipers? One more thing to go wrong.

150 bhp sounds like fun, though. :)

Probably, it's what the service manager told me when I queried the lack of an itemised water pump on the invoice.

(They did give me a £25 refund when I moaned that I was quoted for a water pump in the first place.)

It is, quite. It's a 1.4 "Blue GT" from the last model range.

The current range only has 1 litre cooking models plus the fairly bonkers 200bhp GTi, and nothing in between.

Delaying water pump replacement may require a new engine.

Not all engines are interference engines. On a non-interference engine a broken cam belt may simply strand you at the side of the road until the belt and such are replace, so the cost of waiting is inconvenience and a tow.


Some interference engines have sacrificial rockers. If the belt breaks, the rockers may break before the valves get damaged.

You want fun, then you want a Toyota Yaris. That reliable little car beloved of retired people everywhere.

However not the standard version but the GR with 257 bhp through 4 wheel drive in a car weighing just 1200kg - https://www.toyota.co.uk/world-of-toyot ... /gr-yaris/
