Hi All,
I need a car for work, which will take me several hundred miles up the motorway in reasonable comfort and economy, then a few miles up forest tracks and construction site access tracks, some of them moderately steep, rough or slippery. My budget is up to about £7k, and I like diesels for the economy and reliability (my current Skoda Octavia has just clicked over 200k miles).
I was considering a Honda CRV (the 2007-on model) on the basis of reliability, economy, and the fact that the auto-AWD is mechanical, not electronic. (I am not looking for extreme 4x4 ability, I have to emphasise. Ground clearance is as important as 4x4. I know that the CRV is not exactly a farmer's wagon.)
Then someone gave me a lift in a recent Forester diesel, and I was very impressed. He loves it. According to the specs it should be more economical than the Honda, have better off-road capability, and have all the few accessories I need - in particular cruise control for the (Scottish) motorways and the average speed cameras on the A9. I could afford a 2008-9 diesel model with about 80k on the clock, but not much newer than that...
...and then I started reading around and I keep hearing about DPFs, DMFs, "injector relearning" (whatever that is) and broken cranks. Oh, and I noticed that there are very few 2008-13 Forester diesels on Autotrader with more than 100k miles on the clock! So here are some questions:
1. DPF: How likely is it to fail? What are the implications of failure? How much does a replacement typically cost, fitted, at a main dealer or independent? Can you expect it to last as long as the original? Can you get used ones, and if so it is worth while? Is it practical to remove it completely (could it be detected on MoT)?
2. DMF: How likely is it to fail? What are the implications of failure? How much does a replacement cos? Can you get a non-dual mass replacement? Does failure cause any other damage to the car?
3. What is "injector relearning" and why is it a problem?
4. Broken cranks: I think I read somewhere (I can't find it now) that this problem stemmed from poorly written engine management firmware that fed too much torque to the crank, and that the cure was revised firmware. Is this true, does the revised firmware actually cure the problem, and how can I check whether a given car has the revision?
And I suppose finally: If not a Forester, then what? Back to the CRV?
Sorry about writing an essay for my first post! All advice gratefully received.
Many thanks.
