Had my 7 serviced today (total 9000m, last serviced at 4500m) at local import specialist (Notts)
Paid £117 which didn,t include changing AYC fluid (I was told this isn't required every 4500m and if I specifically wanted it doing it would cost £100 as they have to sub it out to main Mitsubishi agent because of special tooling required)
I know this topic has been covered before in umpteen threads but can someone please once and for all cast in stone what Mitsubishi specify for the AYC fluid change interval as I'm real confused.
Staying on the subject of servicing I remember someone saying they had a set of 'test' questions they ask dealers when shopping arouind to asertain if they know what they are talking about. Can someone please tell me what they are?

I wish it was that simple! If you look at the Mitsubishi Owners Manual, AYC oil is not specifically mentioned although they do talk about differentials! This doesn't help anyway, because the service intervals mentioned don't fit with any of the UK conventions. I don't know who wrote the UK service spec, although I have heard it was Ralliart. They do change the AYC fluid every service, as far as I am aware. I personally would rather cahnge ALL oils more regularly than less, so I will be ensuring mine is cahnged every service.

Ballistic,
As simon7extreme says the AYC fluid change interval is not specified in the handbook ( not for 6's anyway ).
A change interval is specified in one of the e5 technical mauals as being 40,000km ( 24,000 miles).
This change interval was reduced to 4,500 miles by Mitsubishi because of some problems with early AYC diffs.

The AYC fluid change itself is a simple drop and replace service. The only special tooling u need are a large syringe and some tubing.

However, Mitsubishi also recommend having the hydraulic ATF fluid bled and replaced at the same time. This needs the special diagnostic MUT-II to actuate the hydraulic pump for effective bleeding of the system. Nowhere in the e5or 6 technical manuals does it mention this as being a regular service item. It should only need to be done if air has entered the diff hydraulic system , due to a major diff overhaul for instance.
I have only had my hydraulics bled once in 62,000 miles and the diff is quiet and works fine.

If in doubt contact Ralliart/Coordsport for confirmation.

If you go into any Mitsi dealer (pick a friendly one) they can call up the service schedule on the computer and print it out for you. It is a Ralliart schedule and shows what should be performed at what mileage, it is what the mechanic uses when he does the service, there are boxes next to each item for the mechanic to tick as he does them.

Ballistic,

The dealer you went to wouldn't be based in Plumtree, would they ? I had disputes of what should/should not be done when I had my 7 serviced there, just wondered if we're talking about the same place. Email me if necessary....
