OP went from 5th gear to 1st gear at 70mph apparently. eek

I'd have thought that would catapult the engine well into 5 figure RPM, although he said that VW have told him 8500 is the maximum they recorded... maybe that's when the car realised the damage was done and counting any higher was pointless!
If I downshifted to first instead of third at that speed I would know about it, instantly! I'm not sure how anyone wouldn't, it would be massively obvious that you had or massively obvious you hadn't. Surely?

The tricky bit - now they know about it - is that the lease company ask you to “indemnify us against the consequences of anything you do which invalidates the manufacturer’s warranties on the Vehicle”
So long as any work done to the car is done by a VAT registered garage, and uses VW approved parts. You can get the work done anywhere and not void the warranty. (EU law stuff)

A 2nd hand engine...would that still count as a VW approved part? Given VW made it... scratchchin

Are you permitted to fit part worn tyres to the lease vehicle?

Probably as they are consumables.


I guess in the most tenuous way possible an engine is also a consumable too but any future buyer would have to think hooligan driver or mechanical failure /maybe a Friday car walk on plenty more Golf Rs to choose from.

I wonder whether buying it off them, fixing it then selling it might be the cheapest option
That could be the case, however it depends on the OPs situation. These are the issues that would put me off that route though:

- you need to wait until the end of your lease to purchase, so pay 6 months (assuming a 2yr lease for OP) for a broken car.
- store a broken car for 6 months or swallow the repair bill now until sale in 6-9 months.
- the BCA valuation is required in full to purchase, there are no finance options available.
- deal with all the private sale to$$ers or take a lower trade bid.
- selling a MK7 Golf R amongst lots of others.

It's got 5 months left, 2 year lease, I guess I must have gone 5th to 1st because if I had have got 3rd it wouldn't have happened, unless there was something wrong with the engine / gear box already, that's what I'm trying to establish

This is the only ram exceedance recorded

No mess no oil

Did the failure coincide with the over-rev event?

Does the timing of the over-rev match when the car stopped working?

I know what you are saying, 5th to 1st you would know about it, however unless you have actually done it, assuming I did, it's actually a none event, no screeching from tyres, no jolt from the car or engine, no warning lights other than the normal when the engine is off just literally a complete loss of power. It literally just cut out, noisey exhaust, music on, didn't even hear it

Yep that exact momemt, cruised to a lay by which was luckily a few hundred yards ahead.

That's what I am struggling with, the rate/feeling of deceleration would be huge; even if you realised what you'd done, dipped the clutch and ripped the gearstick back out of 1st as quickly as you could.

There must be a system in the VW which stops the above process I wrote happening then.. many, many moons ago I went from the top of 3rd gear in an old RS Turbo into 2nd gear when I was aiming for 4th gear and I knew all about it!! Rev counter bounced around, engine made a screaming wail, which I then emulated... shortly followed by a huge missfire and lots of white smoke.

I think I read on another forum something about software that stops the huge rate of deceleration and locking of the wheels,

This is what's confusing me, I thought I would have kissed the steering wheel if I had gone 5th to 1st at 70mph, but one minute it was there, the next the engine was unresponsive and 'start engine manually' appeared on the dash

Trying to be as honest as possible and recount events as they happened, otherwise people's views are pointless,

No oil, nothing obvious from on top or underneath, and no massive deceleration, to be honest my first thought was the car had stalled when the 'start engine manually' came up,

I had just made a gear change, and I'm pretty sure it was from 5th and I was shifting down, however we are talking microseconds, and I really wasn't concentrating on the gear change as most of us don't, it's muscle memory

Have you ever emergency stopped from 70mph? If so you'll know that you don't "kiss the steering wheel". Engine breaking/locked wheels will result in nowhere near as short a stopping distance so no kissing the steering wheel.




Also as this is he UK with a motorway 70mph limit why were you changing down ? Even to 3rd attempted that's some steep hill you were going up - or possibly the tell tale sign of an engine lacking power maybe a big fault?
Or actually you were really on it and full intention of accelerating hard in 3rd gear beyond the speed limit.

On the above be careful as to what you claim - lease car co could go to BiB showing car doesn't go on track days as it's part of the lease agreement likewise they hadn't called stating they were going to use it overseas as such Mr OP was speeding factually on the UK roads....

ECU has my recorded speed at 70, no disputing that, and no, I wasn't giving it some, I was actually on a dual carriageway where the limit was going from 70 to a 50 and into single lane with traffic, I was gear changing for this reason,

Which actually talking it through, I was more likely going down to 4th, and maybe got 2nd,

Vw can't tell me what gear it was only that it wasn't the right one, like I said hand on heart I don't remember what gear other than I was down shifting, muscle memory, no one actually thinks about it and looks down at the gear stick

There was someone on the VWROC forum that bought a Used Golf R and found out it had a fault logged in the ECU.

http://www.vwroc.com/forums/topic/21811-accelerato...

The car drove 'ok' but they ended up taking it back and getting a refund. The fault they had was "max engine speed exceeded " the ECU logged the date it occurred too.

Ok thanks for the information so far everyone,

From the information provided, I have a question,

VW can't tell me what gear it was in,

They can tell me,
Time
Speed
Rev's max

What's to say my gear change was the cause,

Lets say I did actually change from let's say 5th to 3rd, and for some reason the engine wound up in an instant hit 8500 and blew?

Could something have caused this? Engine buggered anyway? Crazy ECU?

As they can't tell me what gear I was in, it seems odd?

What I'm getting at is, what's to say I put the car into a gear that it should have been capable of, but it failed

What is the 3rd gear mph per 1,000 rpms.
Most performance cars do 100mph in 3rd gear (partly for the 0-100mph time but also as it's a great long gear to smash others out of the park).


If 3rd really was doing 8,500 @70mph then that would mean you'd be doing 5k revs at 40mph.... which isn't correct. 2nd more likely 1st only if you drive a Cerbera

not more than any other mainstream ecu.
It would show something like this.


11837 - Maximum Engine Speed Exceeded: Engine Warranty VOID!
P0219 00 [104] - -)
Intermittent - Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 17
Mileage: <mileage usually in kmph>
Date: yyyy.mm.dd
Time: hh:mm:ss
Speed : xxx kmph
Revs: xxxx RPM
It shows a lot more than the basic fault codes and time that faults occurred.

That's a very good point, I would pursue that if i was you!

5th to 2nd would cause an over rev - I have done it way back in 2004 in a brand new a4 at about 70 ish when I missed 4th completely

The deceleration was huge and the engine rev'd really high, I swapped it back into 4th and drove on - no smoke or flames or engine implosion.

I reckon you maybe caught 1st, and if so - BOOM end of engine.

I was in a friends car when they did that in a 4 speed manual going from 4th to 3rd but got 1st - con rod through the block.
