Hi! I have the V70 Bj 1998 with the 193 hp 5-cylinder turbo engine. We have changed the control unit and it now brings 0.9 bar charging pressure. From the trigger it goes totally well, does not go worse than my Audi A8 with 300 hp, which I had before. Now I want to install a Pop Off. An acquaintance has the same Volvo with the same engine. He installed a Pop Off last week that absolutely doesn’t hiss. It works on etc. – but you don’t hear anything. He installed it on top of the idler by means of a T-piece. It’s not on the valve, a friend had it previously in the Audi S4 20V Turbo where it hissed damn loudly. Is this installation place right or where would you recommend that you install a pop Off? Thank you! LG Peter

Hello, since yesterday my ventilation in my moose has almost completely put down the work. It has made itself noticeable, by a smell after “decomposed electronics”. As an electronician I assumed that possibly a transistor/thyristor on the blower control board has given up the mind. But a friend told me that it can also be a resistance. Can someone tell me how to change it, or if necessary send me a disassembly/installation instruction? Wouldn’t want to pay 800€ at the friendly because he exchanges the whole board, if I can just solder the defective component myself and exchange it. Thanks for your help Sven

Hello, I need your help: our 1997 V70 2.4 144PS has run over 180,000km by now. Except for the climate he never had anything. Since he spent his whole life with us, I can clearly say this. Unfortunately, however, some problems with an unround ride accumulate. It all started after the clutch exchange half a year ago. When starting it occasionally after complete domes, i.e. at the beginning of the acceleration, a large set made. This became better with time. However, three weeks ago he started to jerk slightly in the stand. The speed varied between 600 and 1100 rpm. After the next, somewhat rough start of the engine, the engine jerked very strongly and without interruption. However, it was not regular. Over 3500 rpm, however, the rushing disappeared. In the workshop, however, spark plugs, air filters were read again, … and it was gone. Now it started again. In addition to the jerking now also a strong vibrating. It was not possible to get rid of it with an irregular weight of 70km/min. But in the workshop, there was still a good time to compare.

Hi, since recently my C70 makes slight howling noises from the area of timing belts, V-belts, one hears the noises best when the engine is running in the standing or in the first gear slowly passing a wall. The timing belt, V-belts and belt tensioners were changed at 112000km and now after about 2 years and 132000km further makes me the howling noises from this area, what could be the water pump or?? because that was then not changed. It is a C70 Bj. 2000 2,0T thanks!

So, that eats: – 09.97, current 275,500KM (… na und ?) – 2.5L, 20V, 170 HP, switch (runs / pulls clean, was short on 200, a lame A6 before me ) – Autronic Mistral II seq. LPG system with 77 L tank in wheel mulde (not funzt somehow) – Columba rims with 205/50/16 Hankook (uaaah, ancient), 4-6mm – winter tires on Alu’s (… tires for’n garbage) – level mats (I didn’t even notice) – climate automatic (logo, but doesn’t do, unfortunately) – Tempomat, board computer (must I have) – audio system Volvo SC900 (real bulging !) – Org. el. glass chub roof (tight and funzt) – condition outside: For the old passable, hardly scratches, Macken (except front, paint off) – condition inside: Very passable – I would have made the quite clean before the sale – it’s been interesting.

Hello together, I was always excited about how (hour long) long my car needs 0-100, before last night when I was all by myself, just put the phone behind the steering wheel and put on the country road, simply kept and printed on the recording button, tried 3 times and the best result was this:http://www.youtube.com/watch?v=0Mob06F_rgE for all critics Fans: I did not endanger anyone, was not girls to impress, the mature yet entirely, in the city I can not do that, police can not punish me because no speed exceeded, and also all rabbits and hedgehogs was to bed.. Many greetings

Hello dear Volvo community, I bought a Volvo V70R from priva MJ 98 with approx. 200 000 KM. I thought for a long time because the body had some used tracks but nevertheless closed up. The owner was a trained screwdriver and a Volvofan who sold his whole Volvo collection because of illness. I looked at the car last weekend, and looked at it for 2 hours. Except for the Karrosserie and a Kaputter Nebler was all in order. Today I picked up the car with my girlfriend in the convoy, about 200 km away from home. Tonight I took the car in the garge in the magnifying glass!! Since much of the oil on the oil measuring rod was not even at the lowest mark. The oil cover is also directed at petrol, but it probably happens. The pre-circuiter drove every day maybe 35 km to work and back! So not so far I can find a turbo is a little oily, in the charging air hoses is just an oil film. In the clothing under the cooler package is oil as well as on the forum, just like the turbo is consumed by a lot.

Hello, I hope I’m here in the right forum. Hello, a friend of mine drives a Volvo C70 cabrio with the 2.5T engine. One of the first ones that were built from 2000. The engine has now almost 270tkm on the clock and there are some things that need to be done. The clutch must be made absolutely, the timing belt, water pump also because it loses cooling water, ZKD has to be new and somewhere the turbo leaks, it whistles so nen bissle past the side. The workshop meant that there is a total damage, because the engine goes into the thousands and the car is not worth more. Right you, could be very expensive, therefore it will be made itself and we have decided to take the engine out. We have from April the possibility to bunker the car and to work on it. And if the engine is once outside, you will get comfortable to exchange all parts and to check it out. The question is now, since the head has to go down anyway, what can or should be done right with the valve seat and the valve loop, or if it is enough to make the piston ring again?

Hello, I have a volatile phenomenon, but it doesn’t stop every time. if I press my flasher no matter if left or right, it doesn’t blink, but the flasher just lights up until I take out the flasher. I assume that it is on the relay, if yes, where is the flasher relay?? A small question I would have in addition. If the cam crankshaft sensor has so slow a blow away, and the engine does not start now and then, then the motor control light lights up?? With the antenna ring nothing should normally light up. With me nothing lights up if the engine doesn’t want to start. I know that from other car manufacturers that lights up the motor control light when the cam crankshaft sensor has a blow away, so I ask, because then I know where I have to start looking. Because in addition, I have the problem. Before I forget it, it is a C70 2.0 year 2000 Thanks and a nice weekend!

There is an unergonomic place in the 850: the ceiling light switch. I fiddle every time before I found the thing in the dark, I often catch the single buttons instead of the central toggle switch. Since one or the other may be as good as me, the idea comes to me to install a discreet lighting in the switch. If this works, I would of course also like to introduce it here. I would like to have an extra ceiling light module for this project, so immediately the question: Does someone have one left or can remove one from a battle vehicle? Don’t worry: I would pay for this quite normally, I wouldn’t have given it anything (if someone would spend it for the purpose, but I wouldn’t mind …).
