A year ago I had my 07 Octavia Scout 2.0 TDI serviced with a main dealer where I bought the car, when I bought the car the service was set to "variable". Today a message came up with "service due in 900 miles", Iv only done 8500 miles in this time so it looks like the service has been set to "annual" or fixed

I was not informed at the time that the interval had been changed to annual, what would you do? Im going to ring them for an explanation, I dont think I need another service this soon with the type of driving I do and a variable would go about 18 months between services.

cheers Dave

As far as I know servicing is either variable or fixed mileage, the car doesn't know what date it is.

Variable is just that - the car decides when it wants a service by comparing various sensor readings.

When mine was set to variable the intervals came up much sooner than the theoretical maximum. I ended up switching to fixed.

Rob I was told by the service manager that the service interval was determined by the amount of "starts" to the engine, my driving is pretty identical most of the time so this service message has come up much sooner than the last one.

Before you take the car in, get someone with VCDS to check what the car is set to. Gives you ammo

is discussing a Toareg but is probably similar.

Sounds like it does count the days, fuel consumption and some other factors

Not sure if it does count engine starts.

I don't know the specifics - and it's a good question. Idling probably wouldn't be considered as hard as having your foot to the floor most of the time. However, being on/off the gas in traffic might be.....All I do know is that BMW wrote a complex algorithm and changed it in favour of the simpler fuel consumption figure. The Touareg measurement blocks do indicate a consumption figure. Let's take my numbers as an example:

40 Insp in 1 00km Value=91

So, this is now showing 9100km. I set the system at around 5500miles and am now on 11,000 miles. This is about correct for the miles<=>km conversion

41 Insp in 1 Days Value=456

Counting up. This is the number of days since my car was PDId in the US.

42 Oil in 1 000km Value=15

Fixed interval service performance - not on longlife.

43 Oil in 1 000km Value=30

Max achievable mileage on longlife (30,000km=18,800miles).

44 Insp in 1 Days Value=730

Max number of days before the service indicator will show (2 years).

45 Oil Value= 2 (think this means longlife)

I got this directly from openodb.org

46 Consumption Liters Value=359

I don't know the units on this and this may take some working out. Ideas anybody?

Where did you get the 13,000m for the service from. Real world performance is typically never the same as the max. Was this the dealer telling you that it will be approximately 13,000m when the service light comes on, the manual or another source?

I got round to Ringing the dealership today which is Claybank Manchester and the service manager agrees with me that the service interval has been set to fixed by mistake, Iv arranged to go in and have it re set, Result!
