Not as bad as leaving the drain plug out. First hint is a strange slippery feeling under your feet.

I have that T-shirt, too. Made worse by spilling the overflowed drain pan of dirty and clean oil.

Two of the coil is out from what I gather. Pulling the wire on two of the coils didn't make a difference in the idle. Swapped position with the good coils and the idle didn't change for the bad ones. Will swap them with the S60 2.5T to see if the issue goes away.

I went to get parts off parts cars today to take a break from fixing (making things worse) my own cars today. I found out that the black black exterior door trim on 99 v70xcs is simply glued on with a very strong adhesive rather than clipped on like the 850s. When I get home I'll have to check how the 98s have their trim attached. I pulled the four door trims, and the extension that goes to the fender, but you'd need to be very careful putting them back on to keep them lined up. I guess this might just be one of volvo's "improvements" on the x70 cars....

Other than that I found out the trunk release button above the gas door release is for when the tailgate child safety lock is engaged.

When I removed the first coil from the 07 S60 2.5T, the boot slipped right off as it was a little oily. Well, I didn't know from handling the coils in the S70 that they were 2 pieces. Thought it was a one piece unit. Replaced 2 of the bad coils and while at it decided to hot glue the upper mount :o :lol: . The hot glue worked so well on the large hole of the radiator overflow tank on the Honda Odyssey, going on 5 years I thought why not. There was a lot of vibration and noise transmitted into the cabin during a 30 minute drive so thought it was from the basically solid mount.

In further driving the car something still didn't feel right. Found a 3rd coil with slight condensation in the boot but the body had a hair line crack. Decided to install remaining 3 coils and the engine noise and vibration are gone. The hot glue gun is just a temporary fix but it could well be a permanent solution or as a sort of insert to a new mount.

So basically 3 coils were on its last leg and perhaps the other two were weak. This explains the "P0300 Misfire detected - random / multiple cylinder". Car engine is now quieter, smoother with a little more pep and no vibration at idle.

Have a heavy duty hot glue gun so it flowed into the mount really well and was smooth till I tried to make it even smoother when it was hot with a drywall knife. Was running late so left it in that mess :roll: .

When you talk about the coils being a 2 piece unit, do you mean the coil and the boot?

I find many coils in the junkyard and the majority of them start with a crack on the opposite side from the connector. This will generally spread down the shaft and eventually cause a short. The fact you had oil all over them may well have hastened the end.

Cracks then start elsewhere on the coil body, usually on the RHS of the body from the connector.

I have some that were from a running car. I have tried gluing them with high temp epoxy to see if they still continue to work well. Problem is that the R is running well so far, so don't want to disturb it!

What Speed Signal from ABS module output to dashboard meter speedo input pin signal looks like.

Honestly. Volvo own information is confusing. If you check from ABS pins it shows correctly output being some like
"U= 0 - U Bat Voltage depends on position of front wheel"
But it wont say is it frequency or PWM or Voltage..

On COMBI or meter pin it says its oscillating so.. anyway throwing to trash Volvo own information and just to check and try which one it is..

Its Frequency based and 12V peak to peak (if use multimeter shows some like 6V).
If this helps people diagnosing when ABS module is corroded or something else wrong in their speedo to check if signal is there and is it right.

Well, I decided I could not put it off any longer. I have now started to try and sort and identify many small smaller parts like grommets, screws, plastic clips and a whole lot more. So far I have only managed about 1 and a bit of the smaller storage bins on one set of my 3 sets of storage bins. It has taken me about 4 hours or more, using my old Vida laptop, my 1998 Volvo hard copy parts book and my cell phone to try to identify or confirm identify of parts and their part numbers.

This is going to take an awful long time.............!

I have found some clips I can't identify from memory and even a rubber grommet with a hole in it. After some detective work, I finally found a part number that Vida recognized. It is the rubber lower locator for a P120/P140/P160/PV544/P1800 radiator!!?

I sold my last P120 23 years ago before emigrating to Canada! Yikes.

I also have some clips I don't recognize. I have a funny feeling they may be from my Dad's 96 850 or his 240 before that. Eventually I will post a " Identify that part' thread to see if you eagle eyed folks can help me!

Yup, it should be a 12v square wave. I think they're just basic hall effect sensors.

Yes though i did mean not sensor output but what ABS module generates as output to COMBI/ dahsboard / meter speedo as signal as on these there is not invidiual sensors for speed as this signal comes from ABS module generated by it (or maybe it is just passed from front wheel sensor via ABS module to speedo input on meter directly).

Thos invidiual ABS sensors yes mostly.

btw i just read they claim 25793 pulses per km so / 60 i get 429.. maybe someone wants dig deeper ?
