Hi, I have a Forester XT premium 2010 auto turbo, this annoying 'ticking' sound seems to occur when boost is coming in (at around 2500rpm and usually dissipates at just over 3200rpm). It is actually less noticeable when engine is cold. Jarvis Subaru (australia) came to the party and changed the turbo under warranty but the problem still exits, I have had other Subaru specialist mechanics have a look but they are a little perplexed as well. It is worth noting that at about 2500-3000rpm the ticking sound can be quite loud but by reducing boost via less throttle the sound goes away and comes back if more throttle is used. Could it simply be a turbo bearing noise under load at certain revs?, if so the only fix may be a revised turbo - can't see Subaru going for that. What do you think?. Thanks William.

Hi I have a 2004 forester xt turbo automatic security light blinking will not turn off also I have no spark on the spark plugs any ideas thank you

The security system sounds as if it has been activated. Use the key fob to lock and unlock the doors. This will usually reset the security system

My 2006 subaru forester struggles to accelerate. it chugs along and eventually kicks off.. almost like it needs a good backfire? could be wrong but thats how it feels. i have had it an an auto electrician...

Does it have a turbo? It sounds like it might have a leak in one of the pressurized hoses after the turbo.

Alternatively, an intake leak. Maybe you can use a spray bottle and mist water (or WD40) around the intake gasket and hose connections and see if the idle tone changes.

Why do i have low power on the subaru forester 2003 when its hot?

There is an air sensor on your air filter intake. I would first suggest having this checked for proper function. There are other sensors that can also be checked. Your problem does not sound mechanical

Sidebar: I have always used full-synthetic oil for turbo-equipped automobiles.

Hi, I am a owner of second hand Subaru Forester S type - turbo 2,0 engine ,177bhp, manual transmission, the car is on 120000 km.My question is - should i replace the transmission and differential oil,...

hi yes it is a good idea to replace the oils sooner as it doesnt take much for them to get dirty in subarus, so the sooner you replace the oils the longer the diffs,trans and motors are going to last we usually recomment to customers to do the oils as following, turbo engines around 10,000km, trans and diff oils around 50,000km

Hi there-I have a luxury turbo XT MY06 forester. I have it seviced every 6 months. I have had it since new. My dealership say it is TIME to replace the timing belt but I have only done 50,000 kms. Is time...

A Friend of mine had a Forrester and I'm sure he was told that the belt should be changed around 90 to 100K as a precaution. You don't want it breaking in the middle of no where. Apparently its a pretty expensive job. I would ring around a few Auto repair shops. 50K seems a bit early for such a job.

1. My opinion is to check and replace if necessary the knock sensor, (under warranty of course). (Swap a knock sensor by another good one, and test again the car).
2. This "ticking" sound belongs to the engine at full load, and knock sensor must send this information to the Engine Control Module (ECM), which should decrease the ignition advance in order to eliminate the "ticking" noise!
3. The turbocharger is not the root cause of the problem, because the "ticking" sound still occurs when swapping the turbo!

Anonymous Dec 15, 2010

OK. Can you try to swap the knock sensor by a good one?
Also check all engine components fixations, accessories, cover, and test the engine without alternator belt.
