My vrs has just had an oil and filter change done by the dealer at 1,000 miles at an eye watering £110. Got it back, did a 300 mile family trip to bournemouth 2adults, 1 2yr old and a rammed boot)

Got back, thought long journey, check the oil. It was overfull. Around 4-5mm beyond the max level. All over the slam panel and manual is ' do not overfill with oil' ' risk of damage'

I learnt the car will tell you when its overfull and after two hours of my time and no apology the service guy said its likely a small cupful would show that much and we've adjusted the level and highly unlikely to have damaged the cats/ engine. Nothing else! Not even, sorry heres a free bottle of screenwash!

So,

1. Worth complaining to skoda uk about the poor service?

2. Is a warranty claim likely to be honoured if say the catalysts fail due to the oil?

Someone else will probably chip in with the true likelyhood of damage (which I suspect is slight), but if there is any I'd make sure I had everything in writing in case of a problem down the line.

Do you mean 4-5mm beyond the top of the cross hatch or 4-5mm beyond the kink?  

 

Checked on a dead-flat surface?

 

Engine hot or cold?

 

If hot, how long after switch off?

You're probably ok if it's overfilled by that much but double check with a cold engine and on a level surface and if it is, mention it to the dealer and get them to acknowledge it in case of future issues.

Check twice, left overnight on a flat surface (garage)

It was actually more like 8-9mm on the flat part above the max line.

It will be on the service history as its computerised. Its not smoking etc and no warning lights. It appears to be driving just as it did before. I'm just a bit paranoid after my edn30 starting smoking black smoke on boost at 24k miles which was only ever serviced by vw.

Yep, get the dealership to give you a written explanation then report the matter to SUK, should SUK later down the line withdraw the waranty you've got cause for redress, right now you've got diddle squat.

i don't think that amount will cause a problem.

 

Re: Service history on computer.  Maybe the UK is different but down here the dealership computers don't talk to Skoda HQ or among themselves, so Skoda hasn't a clue what the service history or "noted possible faults" are unless the dealership provides a download from their system.  If the dealership goes belly-up / pulls out of the franchise (quite common in the Skoda network down here) then there's no service record.

 

I'd recommend you get a written acknowledgement that they overfilled the engine - just in case

Written notice is always a good idea.

There is a buffer in filling the oil because they have to account for the possibility that the vehicle will be parked or operated on steep slopes. You'll be fine.

I had a commercial truck with a cracked oil pickup tube, the solution was to add 7 GALLONS of oil to cover the crack until I could get back to a terminal.

At least they put oil in your car, far worse to drain the old oil out and forget to refill it properly as a local dealer did with one of my Dad's cars many years ago! After one long journey the engine wasn't running too good being almost dry and tbe garage denied any responsibility and that car a Rover 800 Vitesse ( pretty fast car in its day and rather nice in Nightfire Red) was never the same again, luckily it was a company car but on the whole too much is better than too little.

You should be fine mate, you need it to be way above the dipstick full level to cause problems,but what you can do is arrange for them to drain and refill at their expense, or refund you your cost
